Last time he was active in this thread was Nov 2019, he was usually very active in the past, even when he didn't make updates. Now I think he might be retired from developement. He made crazy gains since his miner was the only decent software during the 2017 market boom and probably saved up tons of ETH and just living on an island somewhere.
Islands that programmers go to usually have internet connection. Wasting a ton of money like that, I would rather guess he's not alive anymore, or imprisoned. Or maybe lost his hands, eyes, whatever. Of course, these things have very low base likelihood, but other options just don't make any logical sense I can think of.
What hashrate does Ethminer give you for the 3080?
86.5. For 2080 Ti with +300 mem OC it's 52.7.
Was 86.5 mh the fastest you could get with Ethminer?
I didn't do any additional OC outside of what manufacturer did yet. Only power limiting. I'd guess it can do a bit more. Especially since 3090 mem has a lil bit higher frequency and it's based on same memory modules from what I know.
